Abstract
The utility model relates to a transmission device for switching the well plugging device of petroleum wells, belonging to the petroleum drill rig manual plugging device, in particular to a universal manual control device for well plugging devices. The technical scheme is that the transmission device comprises a joint, a double universal coupling, a connecting pipe, a supporting base and a hand wheel, wherein the one end of the joint is connected with the valve rod of a well plugging device and the another end is connected with the double universal couple which another end is welded with the connecting pipe, a connecting pipe is arranged with the supporting base, and the another end of the connecting pipe is connected with the hand wheel. The transmission device has the advantages of simple structure, easy production and simple operation for switching well plugging devices, which can further improve the safety of manual operation on well plugging devices.
Description
Technical field:
The utility model relates to a kind of transmission device of oil drilling switch blowout preventer, belongs to the oil-well rig device of manually shunting in a well, and particularly is a kind of blowout preventer universal manual manipulation device.
Background technology:
At present, in the wellbore construction process, the blowout preventer manual control device that drilling crew uses by 1 joint, 1 movable joint, 1 piece 1 1/2 " drive link and handwheel are formed; when meeting emergency in the down-hole and need shunt in a well; the rotation handwheel, close blowout preventer by drive link, movable joint, a joint.Owing to have only a movable joint, so when well head setting height(from bottom) and rotation direction changed, derrick base and top large pulley thereof can hinder control stick and outwards lean out and do not have fixed support, cause the manual joystick use very inconvenient.
Summary of the invention:
The purpose of this utility model is exactly the defective that exists at prior art, provide a kind of can be in any direction, the optional position implements the blowout preventer universal manual manipulation device of closing to blowout preventer.
Its technical scheme is: the utility model comprises joint, double universal coupling, tube connector, supporting seat and handwheel, one end of joint connects the blowout preventer valve rod, other end welding double universal coupling, the other end of double universal coupling and tube connector welding, connecting rod is provided with supporting seat, and the other end of tube connector connects handwheel.
Effect of the present utility model is: simple in structure, to make easily, and switch is more convenient; Can further improve the safety of blowout preventer manual control.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment:
With reference to accompanying drawing, the utility model comprises joint 1, double universal coupling 2, tube connector 3, supporting seat 4 and handwheel 5, one end of joint 1 connects blowout preventer valve rod 6, other end welding double universal coupling 2, the other end of double universal coupling 2 and tube connector 3 welding, connecting rod 3 is provided with supporting seat 4, and the other end of tube connector 3 connects handwheel 5.
When the needs closing well, rotate handwheel 5, whole manipulation device can be passed to blowout preventer valve rod 6 to the moment of torsion of handwheel 5 by joint 1 very neatly, thereby reaches the purpose of switch well.
